If you need a resistor value which is not in the E series you commonly use; the
Resistor Calculator can be used to determine which two
or three resistors you need to combine to create the resistance required.

The E12 series is the most commonly used, and 61 resistor values
are usually available when purchased as a set.
The E6 Series

| 100R |

| 680R |

| 680K |

There are usually 31 resistor values available in the E6 series when
purchased as a set. The E6 series is a good compromise between the E12 and E3
series.
The E3 Series
There are usually 16 resistor values available in the E3 series when
purchased as a set. The E3 series values are often more convenient than the E1
series values and the E3 series is an ideal choice for hobbyists and home
electronics enthusiast.
The E1 Series
Just 6 resistor values make up the E1 series which makes it a
good choice for those who wish to keep a minimum inventory, and create
resistor values by using combinations of the available resistors when the
need arises. The E1 series is not an official Electrical Industry Association (EIA) standard
but is a logical un-progression of the other E series. It has been
promoted mostly by Richard Torrens of 4QD-TEC
who is a strong advocate of maintaining a minimal inventory of components.
